How to protect yourself against Ransonware - for homeusers and small businesses
Ransomware is a form of malicious software (malware) that enables cyber criminals to remotely lock down or encrypt the files on your device. Criminals use ransomware to extort money from you (a ransom), before they restore your access to the computer or mobile device. Fraudsters will often create authentic looking emails purporting to be from genuine companies in order to deliver the ransomware.
